AMC1303M0520: Implementation difference for DC bus voltage measurement in datasheet and TIDA-01349

Hi team,

In the datasheet of AMC1303M0520, there is a schematic shown explaining how to to use the IC in bus voltage measurements. Here the higher potential is connected to AINP and lower potential to AINN.

However, In TIDA-01349 schematics, for the same purpose, the inputs connected to AINN and AINP are interchanged. Can you explain the background behind this change?

Thanks,

Arun
